Beforesizing a flowmeter it is necessary to convert flow units (i.e. SCFM,LPM, etc.) to actual units. To convert to actual measured volume(ACFM) from standard volume (SCFM) ope the Application Toolspage at www.sponsler.com or use the following formula:ACFM = SCFM x 14.7/Pa x Ta/530SpecificationsAccuracy+/- 1% of full scaleRepeatablility+/- 0.25%Temperature Range-450º to 450º F (-267º to 232º C) standard,1000ºF availableACFM = actual cubic feet per minute measure gas flowSCFM = standard cubic feet per minute gas flowPa = operating pressure in (PSIA)= PSIG + 14.7Ta = temperature in degrees Rankine = F + 460NominalMeter SizeFlow RangeACFM - Magnetic PickupMinimum LinearMaximum LinearExtended Flow RangeACFM - MC Pickup w/ SP717 AmplifierMinimumRepeatableMaximumRepeatableaPPROX.MeterFactor“K” PulsesApprox.Meter Wt.lbs./kg¼" (6.4mm) 0.35 3.5 0.2 3.5 5129 2/1C⁄," (6.4mm) 0.75 5 0.5 10 1842 2/1½" (13mm) 1 10 0.8 12 1772 2/1B⁄," (15mm) 2 20 1.5 20 1475 2/1¾" (17mm) 2.5 28 2.0 30 467 4/21" (25mm) 4 60 2.8 75 203 5/2.51¼" (32mm) 6 100 3.0 100 94 7/31½" (38mm) 8 130 5.0 150 56 8.352" (51mm) 15 250 11 250 32 13/62½" (64mm) 25 450 15 500 17 18/83" (76mm) 40 650 ----- ----- 9 19/8.54" (76mm) 75 1200 ----- ----- 4.6 36/165" (127mm) 150 1800 ----- ----- CF 47/216" (152mm) 250 2900 ----- ----- CF 58/268" (203mm) 330 5000 ----- ----- CF 119/410" (254mm) 650 7500 ----- ----- CF 226/10312" (305mm) 900 12000 ----- ----- CF 345/157
